...again, what to do if one didn't pack a 240+ cordellette and is absolutely bent on the quad anchor. again...although i came up with these on my own over a few years ago, i am also certain someone else out there has probably, but not definitely thought these up before, too...just reposting an old FB post via instagram... 1...don't have a cordellette to construct your quad anchor? Match 2 double slings, fix knots at both ends(with stitching in the knotted loops and clear) and clip into different colored slings...reduce potential shock extension by tying knots closer to the center... 2......make your QUAD ANCHOR belaying more comfortable by off-setting the end-knots to create an upper and lower shelf to clip into and belay off of respectively....NOTES: shown here was done with two different toned double-slings to ensure correct redundant clipping in. To improve smoother equalization, tie stitching inside the knotted loops. To reduce extension, tie knots closer to center with carabiners clipped safely into one of each of the different colored slings. Potential buckling of carabiners over the knot in the event if one of the anchors were to fail.
3......if you are absolutely sold on using the QUAD-ANCHOR, but wondering how to for a 3 point anchor-- here is one way to construct...same principles and notes apply as mentioned in previous posts... NOTES: shown here has been extended off a doubled basket self-equalizing sling(blue) off 2 anchor points and also off a single third point backed up with knot-- and as was done in the previous two posts, with two different toned double-slings(refer 1 n 2) to improve redundancy by clipping into one of each color.
Please note the NOTES.
